Hi everyone,
It seems at some point, something was introduced to the compiler that causes a package to fail to build (specifically
packages\chm\src\chmwriter.pas) with an assembler-level range check error. If you run "make all" under i386-win32 with "-CriotR -a" options, the error is triggered. It only occurs under -CriotR and, notably, it does NOT occur when -a is omitted.

The installer encountered the following error:
Compilation of "BuildUnit_chm.pp" failed
As mentioned, it doesn't show up if -a is omitted.

Ah, sorry for the confusion, but it occurs even if -a is omitted. I got mixed up with something else. So it's probably a simple range check error in the source and not an assembler issue.
